Sadly, you also happen to be right.
Can you tell me exactly what I am doing wrong in my ad because I can't seem to understand why it isn't allowed
I can't help because I don't see an ad. Especially if they won't allow it.
if you can't post it, we can't read it. BPS pointed you in the right direction to the self help center section on ad guidelines. I also recommend you read the entire thing, it has lots of helpful info.
As a newbie, you should also introduce yourself on your local regional board, start replying to posts. When you get a review, you can ask for limited VIP membership so you can use the PM system and read the juicy details of your own reviews.
LLAP,
Swim
She has a review going back to March and it's plainly linked to her handle.
I know I am starting to sound like a broken record, but you've been at this for several years, maybe it's time???
There is no shame in "calling it a day" I knew it was my time to step down when I turned this board over to you, maybe it's "your time" too?
Sadly, you also happen to be right.
You and I go way back, and the newb board is a pretty active board. How about a female host(ess) as well? I'm sure this can be time consuming and I know you love golf, among other things! Some help from a co host would be a good thing.
You've missed a few lately my friend, hope all is well...

There are questions best answered by a provider and other questions best answered by an experienced whore monger. Plus, no one should be expected to be "on the job" 24/7 especially for an unpaid position. I think there are several women who would be great at it, I've already mentioned Debbie several times and I think Steph too has both the temperament and the experience to do a great job.
my post was about adding another host, not about Swim standing back.

If you would like, please PM me a copy of what you tried to post and I will do my best to help.
The most likely reason is a lack of the TER banner on your web site, but there could be other reasons as well. We are a friendly bunch on this board, if you feel more comfortable asking another lady, Debbie or Jaydalee have both been known to be quite helpful. Actually if it were up to me, one of their names would be in red to help pick up the slack from the provider POV
Think about this: The OP is a newbie. She saw FAQ for Newbies and probably thought she was writing to admin. She may not realize we who answer here, are all just members like her.
To the original poster. Definitely check out the link BigPapasan posted for you. TER is kind of picky about their ads. It is not that complicated but you do have to follow their procedures. Chances are once you read that, you may find out what you are doing wrong. You can also click on "myTER" at the top of the page, and then click "mymessageboards." There you should see your post and a reason why it was denied. If you are still unsure, you can use "contact us" at the bottom of the page and ask the TER staff for an explanation.
Also, do check out the self help center as swim mentioned (ignore the other part of his post. You already have your review profile linked to your handle which means you already have the Limited Provider VIP)
Feel free to come back to this board to ask questions.
If you go to My TER then, under the More tab, click My Board Posts so you can see everything you've attempted to post. A moderator will list the reason why your ad was not accepted. I know I did not include my website link on my first post which kept my ad from being posted. Hope that helps!!
Your post is considered rude, trouble-making etc., etc.
